Button Design

Hi,

I'm having some trouble trying to create button design. I can't seem to put the buttons into a group box.

Here's an example of what I mean:

Here's my code:

Code:

---

struct
{
    int    iStyle ;
    TCHAR * szText ;
}
button[] =
{
        BS_GROUPBOX,                                                TEXT ("Colours"),
        WS_CHILD | BS_AUTORADIOBUTTON,            TEXT ("Red"),
        WS_CHILD | BS_AUTORADIOBUTTON,            TEXT ("Green"),
        WS_CHILD | BS_AUTORADIOBUTTON,            TEXT ("Blue"),
} ;

#define NUM (sizeof button / sizeof button[0])


LRESULT CALLBACK HelloWndProc (HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam)
{
        PAINTSTRUCT ps ;
        static RECT rect;
        static int  cxChar, cyChar ;
        HDC        hdc;
        static COLORREF colours[3]={RGB(255,0,0),RGB(0,255,0),RGB(0,0,255)};
        static TCHAR* colour[3] = {TEXT("Red"), TEXT("Green"), TEXT("Blue")};
        static HWND  hwndButton[NUM] ;
        int i;

        switch (message)
        {
                case WM_CREATE:
                        cxChar = LOWORD (GetDialogBaseUnits ()) ;
            cyChar = HIWORD (GetDialogBaseUnits ()) ;
                        for (i = 0 ; i < NUM ; i++)
              hwndButton[i] = CreateWindow ( TEXT("button"),
                                  button[i].szText,
                                  WS_CHILD | WS_VISIBLE | button[i].iStyle,
                                  cxChar, cyChar * (1 + 2 * i),
                                  20 * cxChar, 7 * cyChar / 4,
                                  hwnd, (HMENU) i,
                                  ((LPCREATESTRUCT) lParam)->hInstance, NULL) ;
                        return 0;

                case WM_PAINT :
                        InvalidateRect (hwnd, &rect, TRUE) ;
                        hdc = BeginPaint (hwnd, &ps) ;
            SelectObject (hdc, GetStockObject (SYSTEM_FIXED_FONT)) ;
            SetBkMode (hdc, TRANSPARENT) ;
                        EndPaint (hwnd, &ps) ;
                        return 0;
                case WM_DESTROY:
                        PostQuitMessage(0);
                        return 0;
        }

        return DefWindowProc(hwnd, message, wParam, lParam);
}

>> (HMENU) i

This might not be correct, but I think that this is one problem. You're assigning the button a menu that, as far as I know, doesn't exist, which I'm sure is a problem.

I'll try that

I'm not sure if that's the only problem, but that should certainly have something to do with it.
